◆Air conditioning
●Turn the “A/C” switch ( ) off when it is not needed. Doing
so can help reduce excessive electricity and fuel consumption.
In summer: When the ambient temperature is high, use the recir-
culated air mode. Doing so will help to reduce the burden on the
air conditioning system and reduce electricity and fuel consump-
tion as well.
In winter: Avoid excessive and unnecessary use of the heater.
Usage of the seat heaters is effective. (P. 539)
●Using the Remote Air Conditioning System (P. 535) while the
charging cable is connected to the vehicle can reduce electricity
consumption immediately after starting off by operating air condi-
tioning mainly using electricity from an external power source.
●When setting the charging schedule, selecting the start time set-
ting mode and setting “Climate Prep” to “On” can reduce electric-
ity consumption immediately after starting off by operating air
conditioning before charging is completed. (if equipped)
(P. 166)
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. If there is
improper tire inflation pressure in the tires, the EV driving range will
become shorter, and fuel consumption when in HV mode will
increase.
Also, as snow tires can cause large amounts of friction, their use on
dry roads can lead to increased fuel and electricity consumption.

a system if a light does not come on, or turn off. Have the vehicle
inspected by any authorized Toyota retailer or Toyota authorized repairer,
or any reliable repairer.

• While driving on a curve and for a few seconds after driving on a curve
• If your vehicle is skidding
• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
●In some situations such as the following, sufficient braking force may not be
obtained, preventing the system from performing properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery sur-
face
■If VSC is disabled
●If VSC is disabled (P. 511), the pre-collision brake assist and pre-collision
braking functions are also disabled.
●The PCS warning light will turn on and “VSC Turned Off Pre-Collision Brake
System Unavailable” will be displayed on the multi-information display. • If the front of the vehicle is raised or
lowered

● The vehicle is driven on a road which tilts left or right, or a winding road.
● The vehicle is driven on an unpaved or rough road.
● The traffic lane is excessively narrow or wide.
● The vehicle is extremely tilted due to carrying heavy luggage or having
improper tire pressure.
● The distance to the preceding vehicle is extremely short.
● The vehicle is moving up and down a large amount due to road conditions
during driving (poor roads or road seams).
● When driving in a tunnel or at night with the headlights off or when a head-
light is dim due to its lens being dirty or it being misaligned.
● The vehicle is struck by a crosswind.
● The vehicle is affected by wind from a vehicle driven in a nearby lane.
● The vehicle has just changed lanes or crossed an intersection.

WARNING
●Do not use the system in the following situations, as the system may be
unable to correctly assist you in reaching the target parking spot and may
lead to an unexpected accident.
• In an area that is not a parking lot
• A parking lot that is not paved and has no parking space lines, such as
a sand or gravel parking lot
• A parking lot that has a slope or undulations in the road
• A frozen, snow-covered or slippery road
• The asphalt is melting due to hot weather
• There is an obstacle between the vehicle and the target parking spot
• Using tire chains
● Do not use tire other than that provided by the manufacturer. The system
may not operate properly. When replacing tires, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
● The system may not be able position the vehicle in the set location in the
following situations.
• The tires are extremely worn or the tire pressure is low
• The vehicle is carrying very heavy load
• The vehicle is tilted due to having luggage, etc. located on one side of
the vehicle
• There are road heaters installed in the parking lot to prevent the road
surface from freezing.
In any other situations when the set position and vehicle position greatly
differ, have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
● Make sure to observe the following precautions regarding the exit parallel
parking assist mode.
Exit parallel parking assist mode is a function used when departing from a
parallel parking spot. However, this function may not be usable if obsta-
cles or people are detected in front of the vehicle. Only use this function
when departing from a parallel parking s pot. In the event that the steering
control operates, either turn the system off using the S-IPA switch or oper-
ate the steering wheel to stop the control.
● If exit parallel parking assist mode is mistakenly used in the following situ-
ations, the vehicle may make contact with an obstacle.
The departure function is operated in a direction where an obstacle is
present, but the obstacle is not detected by the side sensors (situations
such as when the vehicle is directly beside a pole).

WARNING
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRC/VSC systems off unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota retailer or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.
● Do not use LTA (Lane Tracing Assist).
■ When parking the vehicle
When parking the vehicle without applying the parking brake, make sure to
chock the wheels. If you do not chock the wheels, the vehicle may move
unexpectedly, possibly resulting in an accident.
NOTICE
■ Repairing or replacing snow tires
Request repairs or replacement of snow tires from any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer or legitimate
tire retailers.
This is because the removal and attachment of snow tires affects the opera-
tion of the tire pressure warning valves and transmitters.
■ Fitting tire chains
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
